Re: [suse-security] severe useradd problem

Hello there,

solved it for my purposes :-)

but I haven't found a reason why it happened.

Decription:

I found out, that i forgot to clear the file /etc/default/useradd.
Due to this the following line seemed to do make the problems in there:

GROUPS=dialout,uucp,video,audio

So users were added to these secondary groups as well.
I removed this line and everything worked fine again.
No file seems to be corrupt.
After that to make it complete in removed all users accidently added to that groups - they shouldn't have been int these groups anyway - silly me.

Still I wonder why that silly thing occured to me.
Seems there ist some kind of limit for a line in /etc/group... or something else similar.

the line of each group ind /etc/group was filled with approx. 400 users - just in case anyone wants to check IF theres really some kinda limit.
I dont want to make any further tests...this was enough action for today :-)

Anyway, thanks for allyour thoughts :-)

Holger
